find many NFTs by their symbol

Is your feature request related to a problem? Please describe.
I need to retrieve the NFT's in a collection. I think that I can do this using the symbol.

Here is what I unsuccesfuly tried:

  const symbol = "POP"
  const symbolBytes = bs58.encode(Buffer.from(symbol))
  const nfts = await programs.metadata.MetadataProgram.getProgramAccounts(
    connection,
    {
      filters: [
        {
          memcmp: {
            offset:
              1 + // key
              32 + // update auth
              32 + // mint
              4 + // name string length
              32 + // name
              4 + // uri string length
              200 + // uri
              4, // symbol string length
            bytes: symbolBytes,
          },
        },
      ],
    }
  )

It returns an empty list.

Describe the solution you'd like
Maybe we could enhance the findMany method to use the search by symbol.
I could contribute with a PR if I understand what my above issue is.

Describe alternatives you've considered
I did not found any other idea about how I can accomplish this task at the moment. Maybe there is a better idea ?

Additional context
I am building a NFT marketplace, that's why I need to retrieve a list of NFTs by collection.

At the moment, I managed to target the main creator using findMany from the Metadata program. It works but I fear that it might be imprecise on some collections.

Can you show how you did that? I'm getting fetch errors when I try it that way.
